FIELD OF THE INVENTION

This invention relates to accessories for personal computers, and moreparticularly to protective accessories for laptop personal computers.

BACKGROUND OF THE INVENTION

As computers become more ubiquitous and as individuals become moremobile, laptop computer sales are on the rise. Individuals areincreasingly requiring computing capabilities and information on the go.As such, today it is customary to walk into a coffee shop or a libraryonly to see large groups of individuals sitting at tables doing work,playing games, listening to music or reading on their laptops. Laptopscan be more expensive than desktop computers due to the lightermaterials, lower voltage parts and mobile components that comprise thelaptop computer. For this reason, individuals are typically protectiveof their laptops, leading to the rise of the laptop accessory industry.

One problem that users often encounter with laptop computers is wear andtear on the exterior of the laptop. Since users often carry around theirlaptops and use them in cafes, restaurants, libraries, on the floor, ina car, on a subway or in any location not intended for computer use, itis inevitable that the exterior of the laptop will be scratched, dinged,dented, cracked, broken, stained, etc. Since most laptop exteriors arecomprised of plastic, there is little one can do to fix such blemishes.

One approach to this problem has been to create laptop covers thatcomprise mostly a sleeve into which the laptop is inserted while it sinthe closed position. This approach solves the problem of protecting thelaptop while it is stored away, but does not solve the problem ofprotecting the laptop while it is in use. This approach, furthermore,requires that the user has to remove the laptop from the protectivesleeve before every use, adding another step to the process of preparingthe laptop for use, which can be a turnoff for users that arecontinually moving and lacking time.

Another problem that users often encounter with laptop computers isoverheating of the bottom of the laptop. The power supply components oflaptops are located on the bottom surface of the keyboard portion of thelaptop. During long periods of use, the bottom of the laptop canoverheat and burn or cause discomfort to the user if the laptop issitting on his or her lap. Further, a user's genitalia are near the lapregion of an individual and there are health hazards associated withoverheating of the scrotum or the vagina. When testicles are exposed toexorbitant heat over long periods of time, for example, an individual'sfertility can be affected. Additionally, if a laptop is resting on topof a piece of furniture, such as a table or a desk, an overheatinglaptop can cause damage to the surface of the furniture.

Therefore, a need exists to overcome the problems with the prior art asdiscussed above, and particularly for a more efficient way to protectthe exterior of laptop computers and to manage the heat generated by thelaptop computer during use.

Additionally, each of the plurality of tabs 132, 134,136 may include a protruding element that extends perpendicularly fromthe raised edge 114 towards the inside surface 116 of the rigid planarsheet 112. More detail on the protruding element of each tab is providedbelow with reference to FIGS. 3-6. The use of tabs allows for the rigidplanar sheet 112 to snap onto the keyboard portion 194 of the laptopcomputer 190 by applying manual pressure, thereby allowing for easy andfast application and removal of the rigid planar sheet 112.

Note that two tabs 132, 134 are located along a bottom of the rigidplanar sheet 112, while one tab 136 is located on a top side of therigid planar sheet 112. Also note that tabs 132, 134 are located onopposite ends of the rigid planar sheet 112 as tab 136 so as to providepressure in opposite directions towards the center of the keyboardportion 194 when applied. This pressure secures the rigid planar sheet112 into the keyboard portion 194.

The raised edge 114 of rigid planar sheet 112 includes lower orretracted portions 142, 144 located along a top of the rigid planarsheet 112. These retracted portions 142, 144 are not raised as high asthe raised edge 114 and either provide an open area for a movable part,such as a hinge connecting the keyboard portion 194 with display portion192, or provide access to a portion of the keyboard portion 194, such asa power connection, a light, a data port, a button or a removable mediadrive.

The raised edge 114 of rigid planar sheet 112 further includes shapedorifices 152, 154, 156 located along a left side of the rigid planarsheet 112. These shaped orifices 152, 154, 156 provide access to aportion of the keyboard portion 194, such as a power connection, alight, a data port, a button or a removable media drive. Also noteshaped orifice 158 (for air circulation) located along the rigid planarsheet 112, shaped orifice 159 located along a bottom side of the raisededge 114 and shaped orifice 160 located along a right side of the raisededge 114. These shaped orifices 152, 154, 156, 158, 159, 160 provideaccess to a portion of the keyboard portion 194, such as a powerconnection, a light, a data port, a button or a removable media drive.For example, orifice 160 may provide access to a CD/DVD drive whileorifice 159 may provide access to an LED light. Note that each orificeis shaped according to the shape of the item to which it is providingaccess.

The raised edge 114 disposed around the circumference or perimeter ofthe rigid planar sheet 112 covers at least a portion of the sides of thekeyboard portion 194 when applied. FIG. 1 further shows an area 162located along the top of the rigid planar sheet 112 wherein the raisededge 114 is either lower or non-existent. Area 162 may provide an openarea for a movable part, such as a hinge connecting the keyboard portion194 with display portion 192. Also note lower edge 164, which is lowerthan raised edge 114. Lower edge 164 may provide access to a mechanism165, such as a latch, for opening or closing the laptop computer 190.

Lastly, note depressions 172, 174, 176, 178 located on the rigid planarsheet 112. The depressions 172, 174, 176, 178 are located near thecorners of the rectangular rigid planar sheet 112. Each depression 172,174, 176, 178 causes a protrusion on the opposite side (not shown) ofthe rigid planar sheet 112. A “foot” or elastic, pill-shaped element(comprised of rubber or plastic) may be adhered to the protrusion on theopposite side (not shown) of the rigid planar sheet 112, so as toprotect furniture or any surface from scratching or damage when therigid planar sheet 112 is placed on it.

Rigid planar sheets 102 and 112 may be manufactured from a variety ofmaterials including metal, such as stainless steel, titanium, aluminumor any metal alloy, rigid fabric, carbon fiber, epoxy resin, graphite,rubber, plastic or any combination of the above.

Plastic covers a range of synthetic or semi-synthetic polymerizationproducts. Plastics are composed of organic condensation or additionpolymers and may contain other substances to improve performance oreconomics. In the present invention, plastic may comprise any one of thefollowing forms of plastic: polyethylene, polystyrene, high impactpolystyrene, polyethylene terephthalate, nylon, polypropylene,acrylonitrile butadiene styrene (ABS), bayblend and polyvinylidenechloride (PVC).

The rigid planar sheets 102 and 112 may be manufactured of the presentinvention can be manufactured from a plastic compound using any varietyof processes, such as injection molding, fusible core injection moldingand thermoforming.

Injection molding is a manufacturing technique for making parts fromthermoplastic material in production. Molten plastic is injected at highpressure into a mold, which is the inverse of the product's shape. Aftera product is designed by an industrial designer, molds are made by amold-maker from metal, usually either steel or aluminum, andprecision-machined to form the features of the desired part. Injectionmolding is widely used for manufacturing a variety of parts and is themost common method of plastic production.

The most commonly used thermoplastic materials are polystyrene, ABS oracrylonitrile butadiene styrene, nylon, polypropylene, polyethylene, andpolyvinyl chloride or PVC.

Injection molding machines, also known as presses, hold the molds inwhich the components are shaped. Presses are rated by tonnage, whichexpresses the amount of clamping force that the machine can generate.This pressure keeps the mould closed during the injection process.

Molds separate into at least two halves (called the core and the cavity)to permit the plastic part to be extracted. In general, the shape of apart must not cause it to be locked into the mould. For example, sidesof objects typically cannot be parallel with the direction of draw (thedirection in which the core and cavity separate from each other). Theyare angled slightly. Pins are the most popular method of removal fromthe core, but air ejection, and stripper plates can also be useddepending on the application. Most ejection plates are found on themoving half of the tool, but they can be placed on the fixed half.

Molds are built through two main methods: standard machining and EDMmachining. Standard machining, in its conventional form, hashistorically been the method of building injection molds. Withtechnological development, computer numerical control (CNC) machiningbecame the predominant means of making more complex molds with moreaccurate mold details in less time than traditional methods.

The electrical discharge machining (EDM) or spark erosion process hasbecome widely used in mold making. EDM is a simple process in which ashaped electrode, usually made of copper or graphite, is very slowlylowered onto the mould surface (over a period of many hours), which isimmersed in paraffin oil. A voltage applied between tool and mouldcauses erosion of the mould surface in the inverse shape of theelectrode.

Fusible core injection molding or lost core injection molding is aspecialized plastic injection molding process. It is used in themanufacture of molded components with cavities or undercuts, which wouldnot be possible with tools having demoldable cores. The process consistsof three essential steps. First, a core consisting of a low meltingpoint metal is poured in the shape of the cavity specified for themolded component. This is inserted into the injection mold in the secondstep and injected with plastic. Molded component and core are bothdemolded and, in the third step, immersed in a heated bath to melt outthe core. The bath temperature is selected to be somewhat higher thanthat of the core alloy's melting point, but not so that the injectedpart would be damaged. Induction heating of the core metal in the heatedbath reduces the melt out time to a few minutes. Liquid core metalcollects on the bottom of the heated bath and is usable for a new core.

Thermoforming is a manufacturing process for thermoplastic sheet orfilm. The sheet or film is heated between infrared, natural gas, orother heaters to its forming temperature. Then it is stretched over orinto a temperature-controlled, single-surface mold. Cast or machinedaluminum is the most common mold material, although epoxy and woodtooling are sometime used for low volume production. The sheet is heldagainst the mold surface unit until cooled. The formed part is thentrimmed from the sheet. The trimmed material is usually reground, mixedwith virgin plastic, and reprocessed into a usable sheet. There areseveral categories of thermoforming, including vacuum forming, pressureforming, twin-sheet forming, drape forming, free blowing, and simplesheet bending.

In one embodiment of the present invention, rigid planar sheets 102 and112 may be manufactured from a material that is a solid color (ormultiple solid colors), a transparent color (or multiple transparentcolors) or may include a pattern or other series of multiple colors in avariety of selections. In another embodiment of the present invention,rigid planar sheets 102 and 112 may include graphics, designs, logos,pictures, or any images that can be applied to the planar sheets. Thegraphics may be embedded in the material comprising the rigid planarsheets 102 and 112 or the graphics may be stamped, painted, stenciled,laser etched, printed, engraved or silk-screened onto the exterior orinterior surfaces of the planar sheets.

In one embodiment of the present invention, rigid planar sheets 102 and112 may be manufactured from a material that dissipates or insulates theheat created by the laptop 190 during use. The material used tomanufacture the rigid planar sheets 102 and 112, such as plastic, maypossess heat isolative properties that prevent the outside surface ofthe exterior cover 100 from overheating. Alternatively, the materialused to manufacture the rigid planar sheets 102 and 112, such as metal,may possess heat conductive properties that quickly dissipate the heatoriginating from the laptop 190. Alternatively, the material used tomanufacture the rigid planar sheets 102 and 112 may possess anycombination of heat insulating and heat conducting properties so as toaccomplish the goal of re-directing the heat emanating from the use ofthe laptop 190 so as not to be directed downwards towards the bottom ofthe laptop. Such redirection of the laptop heat is beneficial as itreduces or eliminates the negative implications of high temperaturesalong the bottom of a laptop, including overheating or burning of aperson's lap when the laptop is sitting on top of a user's lap andoverheating of a table, desk or other furniture, thereby leading todamaged furniture.

Furthermore, shaped orifices 152, 154, 156, 158, 159, 160 may provideaccess to a space 420 (see FIG. 4) between the rigid planar sheet 112and the keyboard portion 194. This space 420 may provide an area forheat convection wherein air is the medium. As the bottom of the keyboardportion 194 is heated, the air in the space 420 is heated while coolerair enters the space 420 via orifice 158 (among others). As relativelyhot air rises, so does the heated air move towards the top of thekeyboard portion 194 to escape as cooler air rushes upwards into space420 to fill the void. In this way, the temperature of the bottom of thekeyboard portion 194 is regulated by heat convection so as not tooverheat.

FIG. 2 is an illustration of a perspective view of the exterior cover100 of FIG. 1, after application to the laptop computer 190. Note thatrigid planar sheet 102 has been applied to the display portion 192 andrigid planar sheet 112 has been applied to the keyboard portion 194.Note also that the rigid planar sheets 102 and 112 can be applied to thelaptop 190 while the laptop is either in the open or closed position.The plurality of tabs 122, 124, 126, 128 of the rigid planar sheet 102,each having a protruding element, allow for the rigid planar sheet 102to snap onto the display portion 192 of the laptop computer 190 byapplying manual pressure, thereby allowing for easy and fast applicationand removal of the rigid planar sheet 102. Tabs 126 and 128 are locatedon opposite ends of the rigid planar sheet 102 so as to provide pressurein opposite directions towards the center of the display portion 192when applied. This pressure secures the rigid planar sheet 102 into thedisplay portion 192.

The plurality of tabs 132, 134 and 136 (not shown) of the rigid planarsheet 112, each having a protruding element, allow for the rigid planarsheet 112 to snap onto the keyboard portion 194 of the laptop computer190 by applying manual pressure, thereby allowing for easy and fastapplication and removal of the rigid planar sheet 112. Tabs 132, 134 arelocated on opposite ends of the rigid planar sheet 102 as tab 136, so asto provide pressure in opposite directions towards the center of thekeyboard portion 194 when applied. This pressure secures the rigidplanar sheet 112 into the keyboard portion 194.

The rigid planar sheet 112 includes shaped orifices 152, 154, 156located along a left side of the rigid planar sheet 112, the orificesproviding access to a portion of the keyboard portion 194, such as apower connection, a light, a data port, a button or a removable mediadrive. Also note shaped orifice 159 located along a bottom side of theraised edge 114. These shaped orifices 152, 154, 156, 159 provide accessto a portion of the keyboard portion 194, such as a power connection, alight, a data port, a button or a removable media drive. Note that eachorifice is shaped according to the shape of the item to which it isproviding access. Also note lower edge 164, which may provide access toa mechanism 165, such as a latch, for opening or closing the laptopcomputer 190.

FIG. 3 is a perspective detail view of a first tab 300 for securing arigid planar sheet of the exterior cover 100 to a laptop computer 190,in accordance with one embodiment of the present invention. The firsttab 300 may describe tabs 122, 124, 126, 128 132, 134 of FIG. 1 in moredetail. FIG. 3 shows that first tab 300 is attached to a top surface 304of raised edge 302, analogous to raised edge 104 or 114. The first tab300 includes a flat surface 306 that slopes inward or extends toward theinside surface 308 of the edge 302. The flat surface 306 connects to thetop surface 304 of raised edge 302. The first tab 300 has a rounded back310 that curves back away from the surface 306 and connects to theraised edge 302.

FIG. 4 is a cross-sectional detail view of-the first tab 300 forsecuring a rigid planar sheet of the exterior cover 100 to a laptopcomputer 190, in accordance with one embodiment of the presentinvention. FIG. 4 shows that flat surface 306 of tab 300 slopes inwardor extends toward the inside surface 308 of the raised edge 302. As thelaptop 190 is inserted into the exterior cover 100, the tab 300 may bepushed back or away from the inside surface 308 of the edge 302 so as toallow for the full width of the laptop 190 to be inserted into theexterior cover 100. The malleable or elastic nature of the materialcomprising the exterior cover 100, such as plastic, allows for the tab300 to be pushed back or away from the inside surface 308 of the edge302 without breaking the tab 300, while allowing for the tab 300 toreturn to its initial shape or arrangement after the full width of thelaptop 190 is inserted into the exterior cover 100.

FIG. 4 shows that after insertion of the laptop 190 into the exteriorcover 100, the flat surface 306 of tab 300 slopes inward toward thelaptop, thereby extending over the top surface 410 of the laptop 190 soas to grip the laptop 190. This positioning keeps the laptop 190 frommoving upwards and exiting the exterior cover 100 since the tab 300grips the laptop 190 to secure it in place. Thus, tab 300 secures thelaptop 190 within the exterior cover 100. The application of enoughforce, however, may force the tab 300 to be pushed back or away from theinside surface 308 of the edge 302 so as to allow for the full width ofthe laptop 190 to exit the exterior cover 100.

FIG. 5 is a perspective detail view of a second tab 500 for securing arigid planar sheet of the exterior cover 100 to a laptop computer 190,in accordance with one embodiment of the present invention. The secondtab 500 may describe tab 136 of FIG. 1 in more detail. FIG. 5 shows thatsecond tab 500 is attached to a top surface 504 of a rigid planar sheet510, and possible a raised edge (not shown), analogous to raised edge104 or 114. The second tab 500 includes a flat surface 506 that slopesinward or extends toward the inside surface 508 of the rigid planarsheet 510. The flat surface 506 connects to the top surface 504 of therigid planar sheet 510 or a raised edge. The second tab 500 has arounded back 512 that curves back away from the surface 506 and connectsto the top surface 504 of the rigid planar sheet 510 or a raised edge.

FIG. 6 is a cross-sectional detail view of the second tab 500 forsecuring a rigid planar sheet of the exterior cover 100 to a laptopcomputer 190, in accordance with one embodiment of the presentinvention. FIG. 6 shows that flat surface 506 of second tab 500 slopesinward or extends toward the inside surface 508 of the rigid planarsheet 510. As the laptop 190 is inserted into the exterior cover 100,the second tab 500 may be pushed back or away from the inside surface508 of the rigid planar sheet 510 so as to allow for the full width ofthe laptop 190 to be inserted into the exterior cover 100. The malleableor elastic nature of the material comprising the exterior cover 100,such as plastic, allows for the second tab 500 to be pushed back or awayfrom the inside surface 508 of the rigid planar sheet 510 withoutbreaking the second tab 500, while allowing for the second tab 500 toreturn to its initial shape or arrangement after the full width of thelaptop 190 is inserted into the exterior cover 100.

FIG. 6 shows that after insertion of the pointed protrusion of laptop190 into the exterior cover 100, the flat surface 506 of second tab 500slopes inward toward the laptop, thereby extending over the top surface610 of a pointed protrusion of the laptop 190 so as to grip the laptop190. This positioning keeps the laptop 190 from moving upwards andexiting the exterior cover 100 since the second tab 500 grips the laptop190 to secure it in place. Thus, second tab 500 secures the laptop 190within the exterior cover 100. The application of enough force, however,may force the second tab 500 to be pushed back or away from the insidesurface 508 of the rigid planar sheet 510 so as to allow for the fullwidth of the laptop 190 to exit the exterior cover 100.
